"I highly recommend Apex-based "A. Maynor Heating & A/C", who replaced my furnace and the entire central air conditioning system (outside condenser unit, inside evaporator coil, and new refrigerant lines) on 7-17-2020 at my Cary house. I also had them install the new outside condenser unit on the opposite side of the house (where it's in the shade, able to operate more effectively) compared to where the original condenser was (in the direct sun). All of their personnel were very competent, polite, prompt, and a pleasure to interact with, from Christy & Tammy in the office, to Carlos & Louis who performed the initial inspection & diagnosis of the original system that had failed, to Norm who performed the house "load calculation", recommended the appropriate new system, and who (since he's a licensed electrician) modified the wiring at the electrical panel as needed for the new condenser location, to Ramon & Christian who performed the new installation, and to Robert who performed the post-installation check and installed a new condensate pump."

"I had them service the heating portion primarily . It seemed to be working harder but nit putting out as much heat as it should . Aaron who has worked on our system did a great job . Since it was a service he checked the whole system , found a weak capacitor and a dead fuse which caused half of the heating elements to not function . Aaron is always polite , very professional and dies nit wast time . He had the capacitor on the truck and did the new Instalation and had to order the fuse for the heating elements . It was a job well done I would add that I am not comparing the cost of the item with other AC companies . The item needed to be replaced , I trust comfort air unless they give me reason not to trust them"

"Russel came out the same day I called to fix our heat pump. He thoroughly diagnosed the problem. He came out the second day and let us know that the company that made our heat pump did not exist anymore and it would have to be replaced. We scheduled the install for Friday. Thursday morning came and he was here early to do the installation of the new system. He wanted to get it done so we'd have heat before a cold front arrives tomorrow. He's thorough, straight forward, a very hard worker, and professional. I'm very glad I chose him to do our repair and replacement. I highly recommend him."

"Very satisfied with the outcome. The house was not occupied while this work was being done, so I was not present during much of the work to observe the installation of system & ductwork, but it worked beautifully once we moved in and began to use it, a turnkey experience. Twice since then we've had questions (e.g., Can we move the ductwork in one part of the attic to accommodate new attic stairs?), and both times they were very responsive and came out at no charge to me, despite the fact that the work was done over a year ago. I've interacted with both Mike (the owner) and with one of his technicians, and have been very satisfied with the level of customer care I've received. I will use them in the future for our heating & A/C needs.

"These guys were AWESOME. I received 4 quotes Cape Fear came in the lowest with exactly what I wanted, Shane was the salesmen we talked more about the days events then the actual project. When he left he felt like an old friend. He Emailed me my quote and came in $2000,00 less then the other guys with a Trane high efficiency (96% 2 stage furnace and new A/C Unit) the other quotes I got was for a single stage 80% plus ac for more money. The Installer Joe and his crew were great. he took time to answer my questions and ran a new return line from the floor and put it in the ceiling, I definitely got my moneys worth. DO NOT HESITATE TO HIRE THEM!!!!!"

"My new Trane heat/a.c. Is up and running. More helpful would be reviews on how things are working two, three years down the road. Also they did a bait and switch on me. I thought I was buying a Trane thermostat but they installed an inferior product. Repeated emails to fix the problem have been ignored."

"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

"Parker and Company Heating and Air completed a discounted tune up at my property and I was highly impressed with the quality of service that was provided. They were prompt, friendly, and spent a reasonable amount of time inspecting my HVAC unit and providing preventative maintenance. I feel comfortable in the future that I will continue to reach out to Parker and Company whenever I need HVAC services. Their pricing was also very reasonable!"

FAQs for furnace / forced air heating system install or replace projects in Smithfield, NC

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.

Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.

With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.

The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.

Consulting with an HVAC professional can help you determine the exact size that's right for your home.

An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.

An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
